Dear Staad expert,
I am modeling a continuous 3 spans curved bridge and wanted to know if the support reaction value from the post processing able to report according the local coordinate of the adjacent beam (or any direction we specify)? I mean to use the tangential direction for bearings as recommended by the code.
Please share some insights. Thank you.
In STAAD.Pro you can specify inclined supports, the orientation of which can be specified by the user. Details are available in section 5.27.2 of the technical reference manual titled Inclined Support Specification. An example on inclined support ( Example 19 ) is also provided within Help > Contents > Application Examples > American Examples > 19 Inclined Supports
Support reactions along the inclined directions can be printed as part of the analysis output file by using the SET command as shown next...SET INCLINED REACTIONPRINT SUPPORT REACTION
Thank you for your great advice, I have tried in a simple model and it works.
Anyway, I found it's a bit tricky to read the result in the Y-axis and Z-axis since the parameter only define reference for 1 axis only which is X-axis. Do you have any hint of how the orientation result reading can be more easier?
Assume that you have defined an imaginary beam member starting from the node in question to the reference point. As you know, this defines the local X of the inclined support system. The way the local Y and Z would be oriented for that imaginary beam, is the same way the local Y and Z would be defined for the inclined support system. If there is any confusion, you may actually define the member and plot the local axis for the member to visually check the orientation of the local axes. Once you figure that out, you may delete the member.
Good solution! Though, it can be a good input for further Staad Pro update to accommodate such graphical feature for this inclined support feasibility.
Thank you for your kind advice.
